One of my favorite simple projects is building two circle wobblers. I love how such a simple object amazes with its motion. The two circle wobbler is an object made out of two circles connected to each other in such a way that the center of mass of the object doesn't move up or down as it rolls. This means that it will roll very easily down a slight incline. It will also roll for a significant distance on a level surface if you start it by giving it a small push or even by blowing on it!
+Nik Cubrilovic discovered last week that Facebook could track your web activities even after you logged out of your Facebook account. After some blatant denials from Facebook spokespeople, Facebook decided to fix the logout issue, but not before +Michael Arrington, on his new Uncrunched blog, made a concise post revealing Facebook's dishonesty: Facebook submitted a patent application for "tracking information about the activities of users of a social networking system while on another domain...
+Randall Munroe, the man behind the web's most popular web comic, XKCD, has always had a knack for getting to the heart of the larger social issues on the web. During the 1st 48 hours after Google+ started letting non-Googlers in, one of the most shared posts within its private walls was his latest comic about Google+:
If you're a lucky owner of the iPhone 4, you know that the upgrade to its camera app includes a front-facing camera feature which acts like a video cam on your computer. Apple, of course, intends the front-facing feature to be mainly used for the FaceTime application which enables you to hold video phone conferences with other iPhone 4 and Mac users who have FaceTime installed on their device. This is all well and good, but there several other ways the front-facing camera can be used.

People ask me all the time, "Nick, what are the best blinds for my home in terms of Wood vs. Faux Wood?" Well the answer to that question is not so cut and dry. However, I can help steer you in the right direction. In this post, we will examine the pros and cons of both wood and faux wood blinds to help you make your decision.
Ladies and gentlemen, I have a confession to make, in case you haven't noticed already: I'm a little reticent about building decks. I've only posted two on this blog, one of which was made by someone else. I have a few thousand cards. Why not make use of a few?

This article will show you how to make a shutter release cable for a Canon camera. It took me about half an hour once all of my materials were gathered. I came in at a total of about eight dollars. It has three switches and buttons. The black button on mine triggers the auto focus. The red button triggers the shutter. Finally, the switch triggers the bulb mode, or long exposure. This can be used to take astronomical photos that show the movement of the stars in the picture. The release cable ...
Outside the realm of politics, where opposing sides are quite passionate and quite disagreeable, there are few areas in our society quite as divisive as Twitter. People who like Twitter love Twitter and are relentless in trying to co-opt the people they know into joining (this is both altruistic and an unsubtle attempt to boost followers).
Facebook is constantly evolving, and lately it seems like a bad thing, at least for its users. First, you had to opt out of Instant Personalization, which shared your personal information with Facebook's partner sites. Then, you had to take drastic measures to secure your home address and mobile number from third-party apps and websites. And now?—Now you need to opt out of Facebook Ads.
Nothing on the web is ever private. If you thought you can control your privacy, you were wrong. Websites may give you security options to better hide your information from the world, but ultimately your privacy resides in the hands of the website itself. We've seen how websites let ad companies track our private usage. We've seen how Facebook mucked up their privacy controls. We even saw how websites like Gawker are prone to hackers stealing user information. And now, Etsy has made what was ...
Facebook is at it again. First they invaded your privacy with Instant Personalization, now they plan to take it a step further with their controversial plans to share users' home addresses and mobile phone numbers with third-party developers and websites.
You know it's crazy out there when governments start blocking social websites like Facebook, Twitter and even YouTube. But that's what happened in Egypt, when tens of thousands of anti-government protesters took to the streets on Tuesday (January 25th) in hopes of ending President Hosni Mubarak's 30 years of authoritarian power.
Sputnik, Apollo and the Space Race. If you watched the State of the Union address last night, you probably heard President Barack Obama mention those three things.
Sputnik was the very first man-made object to be sent into space. Though it was a truly epic accomplishment, all this Soviet sky surfer actually did was transmit a constant beeping noise back to the surface.
Just about every household gadget we own runs on 1.5 volt batteries of one size or another. Wouldn't it be great if you could reuse all of those dead AA, AAA, and D batteries after they've passed on? It turns out you can make a simple circuit called a "Joule Thief" to reanimate the undead flesh of your deceased batteries and create a zombie battery.
I feel like doing a bit of chemistry today, how about you? To my knowledge, thermite is the hottest burning man-made substance. Thermite is a pyrotechnic composition of a metal powder and a metal oxide that produces an exothermic oxidation-reduction reaction known as a thermitereaction.
We've all made them. I remember making hundreds of paper snowflakes when I was in elementary school. You take a piece of paper and fold it in half, then fold it in half again. You now have a piece that is one fourth the size of the original. Now you fold it in half diagonally. You then cut slices out of the edges of the paper, and unfold to find that you have created a snowflake. The resulting snowflake has four lines of symmetry and looks something like this: If you fold it in half diagonall...

Welcome back, my greenhorn hackers! Although we have focused primarily on technical hacks here, social engineering can sometimes be especially effective. This one requires a bit of technical skill, but not too much. In addition, it's limited by how specific a target you can choose—but it will work.
If you've seen ParaNorman or Fantastic Mr. Fox, then you have some kind of idea of what stop-motion animation is. Basically, these artists make objects, or small figures, appear to be moving on their own by manipulating and repositioning them in the smallest increments, then capturing each frame after doing so. When all the frames are compiled together, the final product is something spectacular like The Nightmare Before Christmas, which took roughly 109,440 frames in all.
Camping in the rain sucks. It's not enough to deal with your clothes and tent being soaked—it makes starting a fire nearly impossible if you're not carrying waterproof matches. You can buy them pretty much anywhere that sells camping gear, but if you've got regular matches and a candle at home, they're just as easy to make yourself..
If you've ever used IFTTT, you know how well it can automate your online world. The premise is simple—If This, Then That—but the results are powerful. From automatically printing images based on hashtags to getting around Twitter bans, the service is quite useful with a wealth of possibilities.
Slide to left, slide to the right, one hop this time. Okay, so maybe those are some of the dance instructions for the "Cha Cha Slide", but sliding and swiping on your Samsung Galaxy S3 can become so much more than just a simple gesture.
While the Galaxy Note 3 and Galaxy S4 are enjoying their official KitKat updates, those of us with Note 2s are left to play the waiting game. While we know our devices will eventually see an update to Android 4.4.2 KitKat, it's unclear when an official update for our devices will come.
Editor's Note: The claims by Vani Hari which were originally detailed in the article below about azodicarbonamide were unscientific in nature. This article has been updated to reflect that and provide more scientific context on the issue.
Not many people use film cameras anymore, so it can be hard to find the materials to develop your own photos at home since most local camera stores are closing. But it's actually relatively easy to make homemade developer, and you can make it with a few relatively common ingredients.
Recently, Google unleashed the Chromecast development kit, which lets developers add Chromecast streaming functionality to their own apps. However, there aren't many apps with Chromecast capabilities yet, and big companies and devs are still working on polishing their final products.
We've all heard our fair share of roommate horror stories, or have some of our own, because we never truly know who someone is until we've lived with them. Cohabitation issues generally revolve around things like bills, chores, cleaning, and groceries. Approaching a roommate, especially an adult one, to remind them to do their chores can be an anxiety-ridden and daunting task. After all, we're roommates, not parents!
There are a lot of cool things in iOS 7, but there are also a lot of annoying things about it. One of the biggest issues I have is Apple's stock wallpaper options. I was really hyped about the new dynamic wallpapers, but they turned out to be a real disappointment because of the new interface.
This year, like every year before it, Black Friday sales are starting earlier than ever. A lot of stores will be opening their doors as early as 5pm on Thanksgiving to get a head start on the madness (and it really is madness). As we've discussed in the past, one of the keys to emerging victorious on Black Friday is to plan, plan, plan. So, we've compiled some of the best deals in tech, gadgets and appliances to help you prepare for battle.
With only a few days left until Halloween, your options might be rather limited if you still don't have a costume. You may have laughed while some people spent the entire month of October painstakingly crafting their ridiculously detailed costumes, but now that the big day is so close, the joke's on you because you still have nothing to wear.
Let's face it, the stock YouTube app for Android kinda sucks. It has limited capabilities, at-time wavering connectivity, and the pop-up player it comes with is just not very good. If you want to enhance your mobile YouTube experience to how it should be, the answer lies within a third-party app called Viral HD YouTube Popup Player by Android dev Mata.
The closest I've ever been to first class was when I was a young kid running up and down the aisles on a long international flight. I remember being in awe of how big the seats were and how much food was available. Ever since that moment, I've made it my life goal to earn enough money to make first-class flights a regular occasion.
